If the water damage is small, such as small patches, you can paint over the area. To prevent mold growth, roll on a coat of an antifungal primer beforehand painting. However, if the damage is more extensive, you may have mold, and the plaster will be compromised. You’ll have to replace the plasterboard.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

Venetian plaster is very easy to maintain. As long as your plaster is properly sealed, you can safely wipe it down with water and mild soap to remove any scuffs or stains. And if your plaster wall cracks or chips, you can often simply patch it rather than replastering the whole wall to restore its appearance.
